Hi Elaine, After flipping, if I could save say "file1, file2, file3" as "file1_flip, file2_flip, file3_flip" there should not be any issue of overwriting the original files. I could save mrc files individually after flipping but for saving many maps a command line would be helpful.

Hi Rayees, Elaine suggested the way to process many files and write a new file for each by using the "foreach" option of the open command. The only other way to write out several map files in one command is save myflippedmap_%d.mrc models #1-20 which will save myflippedmap_1.mrc, myflippedmap_2.mrc, myflippedmap_3.mrc, .... In general if you want to do processing of many files you either use Python code with ChimeraX or these few limited capabilities like "foreach" or this "%d" filename. The ChimeraX command language is not a general purpose language with looping statements and variables. Tom

Hi Rayees,

With the "foreach" approach, you would not be using the commands multiple times individually. The cxc file would just have a single "volume flip" command and single "save" command, and then the "foreach" mechanism would take care of executing it on each input file and using an output file name based on the input file name, as explained in the description of that option.

Hi Rayaees, You could have used a ChimeraX command script (.cxc) and opened that .cxc file with the "foreach" option of "open" to open each input map file individually, then flip with "volume flip", then save the result with "save", then do the next one, etc.

Hi Vincent, The "foreach" option is not inside the cxc file. First you make the cxc file. Then you use the "open" command (with the "foreach" option to specify the input data files) to open the cxc file. See the help, which actually has an example: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/open.html#forEachFile> Here is another example. The cxc file (let's call it blah.cxc) could contain volume flip save $file-flipped.mrc Then you would use command open blah.cxc foreach /My-Path/*.mrc I hope this helps, Elaine ----- Elaine C.

Hi Elaine,

this would very very useful. To make sure I get it right, would a script like this work:

#flip-maps.cxc open foreach /My-Path/*.mrc volume flip save /My-Path/*-flipped.mrc

thanks. Vincent
